  • Humans infected by origin zombies will receive a very high amount of health power, resulting sometimes higher than when evolving into an origin zombie which has 7000 health. Therefore your hp will be reduced if you had more than that.
  • Despite the name, there are no zombie characters appearing in Zombie Giant. Only the bosses from Zombie Scenario make an appearance instead.
